Keystone MRP or ERP
MRP and ERP are not the same purchase
A question worth settling before anybody books a demonstration, because it decides which shortlist you should be building.
MRP answers two questions: what has to be made, and what has to be bought, in time for the orders you have accepted. It works from your order book, your bills of material and your stock.
ERP is a category, not a capability. It usually contains MRP, and adds finance, sales, sometimes payroll and HR. The manufacturing part of an ERP is often thinner than a dedicated MRP, because it is one module among many.
A manufacturer can need MRP without needing the rest. If your accounts work and your payroll works, replacing them to get better production planning is an expensive way to solve the wrong problem.
Choose MRP when
Production planning, material shortages and job costing are the problem, and your finance system is not. You want the manufacturing part to be deep rather than broad.
Choose ERP when
You are replacing finance as well, or you need one supplier accountable for everything, and you accept the manufacturing module will be shallower.
What Keystone is
MRP, deliberately. It runs manufacturing operations and integrates at the boundary. Your ledger stays where it is.
The honest catch
Our accounting integration is still being built. If you need invoices posting automatically today, ask about it on the first call rather than the last.
